So, I've got a 10g tank with a few sps frags in it; I just got my test kits for Ca and Alk so I tested them today: 5.8dkH and 340ppm Ca. I'm not sure if I want to use lime or B-Ionic to raise my Alk/Ca levels. Should having such a small tank effect my decision? Right now I'm leaning toward B-Ionic because it sounds a little safer and sounds like a lot less hassle, also with a small tank 1 set of solution will last a lot longer. If I start dripping kalk how often should I test the water to begin with, and how soon should I notice a difference; also, same question for B-Ionic.
